CHANGEABLE EXHIBITOR FOR CARS.

Application filed March 18, 1922. Serial No. 544,879.

T 0 all whom it may concern.

Be it known that T, DIRK A. KLEIMAN, a subject of the Queen of Holland,residing at Ogden, in the county of Weber and State of Utah, haveinvented certain new and useful Improvements in a Changeable Exhibitorfor Cars; and I do hereby declare the following to be a full. clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a changeable exhibitor for railway cars,particularly of the urban and inter-urban type.

One object is to provide an apparatus of this kind which is controlledby a novel means from an obstacle on a trolley wire, the trackway orotherwise disposed in the path of travel.

Another object is" to provide such an apparatus having a novelescapement means operable by mechanism cooperating with obstacles inthe'path of travel.

Another object is to provide a springactuated exhibitor having a motoroperable to wind the spring, and a switch in the motor circuitcontrolled by operation of the apparatus.

It is further aimed to provide a novel means for paying out andrewinding a flexible exhibitor member or tape.

The invention aims to provide an exhibitor of the general constructionand having the features and details hereinafter described withreference'to accompanying drawings illustrating one practicalembodiment. Additional objects and advantages will become apparent froma consideration of said description and drawings.

Like reference characters designate like or similar parts throughout theviews of the drawings.

The improvements are shown as associated with a street car at A. As theinvention is capable of application to cars generally, such illustrationis to be taken as conventional. The trolley or overhead feed wire of thecar A is shown at B as engaged by the wheel C carried by trolley pole D.One of the usual transverse supporting wires for the wire B is shown atE.

An' exhibitor per se is illustrated and may be mounted at any suitablelocation within the car A as at the front or rear thereof in a positionfor view by all pas sengers. The exhibitor may have a casing insuperposed sections 10 and 11 and within the section 10 aplurality ofspools or drums 12 are journaled'to turn on vertical axes. Said spools12 are preferably removably slecured in place in any suitable manner. Tothis end and as shown in Figure 14, plates 13 may be fastened to thebottom wall of section 10 and of such size as to form end flanges ordisks for the drums 12, equivalent to the end flanges or'disks 14thereof.

and have stub shafts 18 to mount the same which are journaled in asupporting wall 19 of said sections. Coupling disks or plates 20 areprovided on the stub shaft 18 below support 19' and provided therein areconical sockets 21 to be engagcdliy a latch 22, having a correspondinglyshaped conical; socket, and which latches are slidably mounted inrecesses 23 of the cores of the spools 12 and urged outwardly byexpansive coil springs 24 disposed therein. Slight movement of thespools 12 intermediate the plates 13 and. 20 is permissible to permitattachment and detachment of the stud 15 with the socket 16. Anysuitable means may be provided to couple the spools 12 tothe plates 20.for unitary movement and tothis end, a: pin 25 may extend from. eachplate 20 and enter radial slots 26 inthe flanges 14. It will thus berealized that the drums12 may be readily attachedand detached from theplates 20 and13.

elongated tape or ribbon 27 is provided which may be. divided intopanels 28 containing eithibition matter, for instance atit-he top,thereof a name of the street or avenue or other-location forming thenext stop and below which suitable advertising matter may, if desired bedelineated. This tape has one end secured removably or otherwise to eachof said spools 12. To the left, at thev front, a panel may be providedat 29 and have delineated thereon Next stop to form a key cooperatingwith the stop indication at the top of the panels 28. In actual use, thetape 27 will contain panels 28 for each block along its route so thatthe device will serve sufficiently as a street'indicator as well as aneffective advertisement I Attention is called to the fact that the advertisement cooperates with the street indication, inasmuch as itrelates to a business or profession adjacent the particular stopindicated on the panel 16. The tape 27 is adapted totravel across andfor exposure at an exhibiting opening 30 in the section 10.

In order to properly guide the tape 27, suitable idler rollers may beprovided within section 10 as at 3-1. In order to connect the spools 12and'ta pe for removal from thecasing, the front" wall and end wallsthereof may be removable or hinged as is obvious.

The tape is adapted to be driven positively and by any. suitable means.To this end, a spring motor may be employed utilining the shaft 33 towhich one'end of a clock spring 34'is fastenedand which spring islocated within a suitable casing 35 and which has its other end securedthereto as at 36. Casing 35 has a sleeve 37 in which the shaft 33 isjournaled and which sleevein turn is journaled in the support 19. Formedintegrally with or otherwise on-the sleeve 37 is a bevel gear wheel 38.

In mesh with the gear wheels 17, are bevel gear wheels 39 keyed tosuitable shafts 40, ournaled in hearings 41 rising from the supportingwall 19. The inner portions of the shafts 40 are reduced as at 41 andkeyed or splined thereto and ,slidable on the portions 41 are bevel gearwheelsp42. The wheels 42 are adapted to mesh one at a time andselectively with the gear wheel 3 r-iny'suita-ble means maybe providedto accomplish the shlftmg of the gear 42.

F or instance a yoke'isprovided at 43 having forks 44 engaging the gears42 in such manner as not to. interfere with. rotation thereof. Yoke 43is part of a lever 45 which may be journaled to swing horizontally-asfrom a shaft 46 and which may have a manipulating-handle at- 47. T heconstruction described forms a means whereby the motor 34 may wind thetape 27 for forward or reverse movement-towards the'opening The casinglOniay have anopening at 48 to permit insertion of the handof theoperator to grasp the handle 47.

A main shaft 49 is journaled in "the upper and lower walls ofthe section11 and extends into the; casing '10. Shaft 49' is adapted to be drivenin the same direction as the 318.1% 33 and is in alinement withthelatter. Shaft 33 practically forms an extension of said shaft 49.Secured to the shaft 49 is one end of a clock spring 50 whose other endas at 51 is secured to the section 11. .Journaled on'the shaft 49 is aworm wheel 52 in mesh with which. is a worm 53 on ashaft 54 adapted tobe-driven from motor 55, preferably of the electric type, in order tosimultaneously drive the shafts 49 and .33 and thus simultaneouslyrewind spring meters 34 and 50. Worm wheel.52 has an inner gear rack 56with which a pinion or gear wheel'57 meshes and which also meshes withthe gear wheel 58 keyed to the shaft 49. Loose on the shaft 49 belowgear wheels 57 and 58 is a large gear wheel 59-to which a stud or shaft60 is rigidly fastened and on which gear wheel 57 is journaled. Belowgear wheel. 59, a ratchet whee-l. 61 is fast on shaft. 49 andcooperating therewith is a spring pressed pawl 62 journaled on the stud(it). When the spring 50 unwinds, its motion is transmitted through thegear wheel from shaft 49 to gear wheel 57 and thence to gear wheel. 59.When the spring is wound. shaft 49 is turned throught-he turning of theworm 53, worm wheel 52, gear wheel. 57 and gear wheel 58, the pawl 62permittingfa slip con nection of the wheel. 59 relatively to-shaft 49.

Shafts 33 and 49 are. not positively connected as a single shaft sinceat times they are required to move independently. To this end, the shaft49 may have an exten sion 62 journaled in a socket 63 in the shaft 33.To this end, a pawl 64 is pivoted at 65 to the shaft 49. This pawlcooperates with teeth of a ratchet at 66. The ratchet 66 is positivelymoved by the pawl 64 when shaft 49 is turned to wind the spring. Whenshaft 49 turns in an unwinding direction, it moves independently of andrelatively to shaft 33 during which action the pawl 64 freely slips overthe teeth of ratchet 66. In order to prevent reverse rotation of theshaft 33, a pivoted pawl 67 is provided within the casing and engagesother ratchet teeth of the ratchet 66 as at 68:

Through expended motion from spring 50, shaft 49, through the medium ofgear wheel 59 and a gear wheel 69 keyed on the shaft 46 within thesection 11, shaft 46 is turned. Keyed on shaft 46 is a gear wheel at'70. Journaled on a vertical axis within the section 10 is a shaft 71which may carr one or more feed rollers 7 2 provided witi projections 73adapted to enter projections 7 4 provided along the edges of the tape27. Shaft 71 is adapted to be driven. in either direction from the gear70 in order to turn the disk 72 and move the tape 27 through positiveengagement of the teeth 73 in the openings 74. Thus the shaft 71 mayhave gear wheel thereon as at 75 above the supporting plate or wall 19.

To provide for reverse rotation of the shaft 71, a lever has a pluralityof gear wheels 76 and 77 journaled thereon as at 78 and79. It will beseen that one of the gear wheels 76 or 77 is in engagement with the gearwheels 70 and. 75, and the other gear wheel is disengaged there-from.Such engagement will drive the shaft 71 in one direction. When the lever45 is shifted, the other gear wheel 76 or 77 will mesh with i the gearwheels 70 and 75, thus driving the shaft 71- in the opposite direction.

A suitable escapement mechanism is associated with the parts describedand to this end a shaft 80 is journaled as in bear- 81 within casingsection 11. A gear .cel is keyed on said shaft 80 and ice with a gearwheel 83 keyed .d shaft 46. At 84, a. ratchet wheel en shaft 80 withwhich a de cooperates. Detent 85 is journaled t and has a lug 86 adaptedto the teeth of the ratchet wheel 84. ted with the detent or arm 85 is ai: link 87 pivoted at 88 within casection 11. Detent 85 has a hook end89 :{e overthe detent 85 when in en ent with the ratchet 84. A spring 90the arm 87 into position engaging the 86. 'Detentarr'n 85 rests on a cam91 keyed to shaft 80 so that Said cam will prevent too rapid return ofarm 85 to normal position, thus controlling the period of escapement. Aspring is provided at 92 to normally urge the arm 85 into engagementwith the cam 91. Adjacent the cam 91, a gear wheel 93 is keyed to theshaft 80 which meshes with a gear wheel 94 keyed to shaft 46.

Secured to the detent is a wire or cable 95 which is guided on the carin any suitable manner as by one or more pulleys 96 and which passesexteriorly of the car and is secured to a lever 97 pivoted at 98 on thetrolley pole D. A spring 99 is connected to the pole and to the lever 97to retain said lever in a normal position against a stop 100.

Along the route traversed by the car A at each street or stop, asuitable abutment is provided to tilt the lever rearwardly which therebydraws the cable 95, elevating detent 85 to release the escapement. Fromthe wire E may be supported, one at each side street or intersectionbetween a main street, an abutment plate 101, disposed in the path ofmovement of the lever 97.

A suitable switch for motor is provided. This motor is shown in anelectric circuit in Figure 13.- The source of current uti lized is shownat 102 having a conductor 103 leading to the motor and a conductor 104leading to a contact 105. A conductor 106 leads from the motor to acontact 107. The circuit through the motor 55 will be closed uponengagement of contacts 105' and 107. As to theswitch proper, contact 107may be stationary and arranged in suitable insulated relation on the topof section-11. Contact 105 is also disposed on and insulated from thetop of the casing 11, being pivoted as at 108 to swing into engagementwith contact 107. Contact 105 'is normally urged into a disengagedposition against a stop 109 by a contractile spring 110. The switch isadapted to be closed at suitable intervals and to this end a gear wheelmay be provided at 111, journaled on a bolt or stub shaft 112 to the topof section 11. Gear wheel 111 is driven by a gear wheel 113 meshingtherewith and keyed to the shaft An abutn'ient 114, preferably ofinsulating material, is disposed on the gear wheel 111 so that as thegear wheel 111 turns, abutment 114 will strike the contact 105 anddepress or swing it into contact with the contact 107. After theabutment 114 passes over contact 105, its spring 110 restores it tonormal or open circuit position.

in practice, the motor 50, through its shaft 54 and gearing drives thegear 69 and shaft 46 and gear wheel 70. The latter. through the mediumof the selected gear 76 or 77 drives gear wheel 75 which drives shaft 71causing the disk 72 to cause travel of the tape 27 in the appropriatedirection. The

motor 34' atthe same time expends its energy so as to wind the tapeabout one of the spools 12 to the same extent that it is unwound orunwrapped from the other spool, thus maintaining it in a taut conditionacross the opening 30. The winding action of the spring 345 is of courselimited I to the amount of tape fed by disk 72 under control of theiroperating gearing and motor 50. At the desired time, the tape is adaptedto be moved in the manner stated but normally it is stationary. WVhen itis desired to operate, cable 95 is drawn through engagement of lever 97with the abutment 101 thus elevating the detent 85 and releasing'theescapement mechanism, permitting the parts to operate until the cam 91moves from the position of Figure 12 to the positionof Figure 11, wherethe parts are again locked against movement by engagement of arm 86 withratchet 8-1. As the parts operate, the contacts 105 and 107 areappropriately engaged at desired times to actuate motor 55'to rewind theshafts 49 and 33 through the medium of the worm 53, worm wheel 52 andappropriate gearing, pawl 64 and ratchet 66. It

i is to be understood of course that the means for operating thedetentshown is by way of example only and that other means may be usedor. substituted therefor. For instance a means may be employed beneaththe car as illustrated in Figures 15 and 16. In said figures,'theequivalent of cable 95 is shown at 115 passing through a suitable tube116, which may be rigid and secured to a part 117 of the truck of thecar. A bell crank lever 118 is pivoted to the sleeve 116 as at 119 andcable 115 is connected to one arm of said lever. A resilient or springsection 120 is provided in the cable 115 so that slight vibratory actionof the lever 118 will not draw the cable sufficiently to release thedetent 85. The other arm of lever 118 is adapted to engage trackobstacles 120 disposed at suitable locations along the roadway. With theengagement of levers 118 with the track obstacles, the levers are tiltedwhich exert a drawing action on the cable 115 and accordingly elevatethe detent. 85.

Changes in the details and principles may be resorted to within thespirit and scope of the invention since merely one practical embodimenthas been illustrated and described.
